Some notes about the missions:

M1: As others said fighter jump drives hadn't been developed yet. It would make more sense if the ones escaping to the jump node instead tried to annoy your wing with ML16+Furies.

M2: Good mission as far as player interaction is concerned, but the scale of the battle leaves a little to be desired. There are way too few GTA fighter wings present (considering that you're dealing with an Orion + a double installation) and conversely also too few Shivan wings. It would be a challenge to script a larger-scale fighter vs fighter AI battle without it impacting player's own challenge too much, but it's something to consider. Lucifer also fires no shots in the first stage of the battle - it could take a couple shots at Orion on its way to soften it up for bombers. Leviathan going down to only one beam from Lucifer is silly, as is Lucifer's accompanying Lilith staying so far away from the heat of battle.

M3: Nothing wrong with it.

M4: Freighters should have their fighterbay departure paths restricted to avoid collisions with Eva's hull around its fighterbays. Beta bonus objective and that entire attack is pretty weird considering that 1. they would be a legitimate threat to Eva if properly escorted 2. they do not depart, so getting the objective happens 100% of the time. I'd suggest replacing them with Athenas with Stilettos + Interceptors and setting them to depart a short time after you deal with the fighters.

M5: This mission is completely trivial in its current incarnation. I'd expect the highest difficulty to throw a legitimate challenge of balancing keeping yourself alive vs keeping Eva alive. If you don't want to throw more GTA forces at the player, I'd suggest stripping friendly forces instead (less fighters, no Cain on patrol, lower starting hull on Eva).

M6: A smart selection of loadout and starting orders for AI makes this not only very easy, but also completely uneventful past the first 30 seconds. I honestly have no idea how to improve this mission without completely overhauling it, but it really sticks out like a sore thumb in its current incarnation.

M7: I'd expect this mission to be just as much about protecting Cain as destroying all escaping transports before they run far past the cruiser and escape, but nope, it's just about protecting Cain. There is one extra transport 14 clicks away from the second-to-last one, which is pretty silly. The aforementioned second-to-last one could also be moved a little to the front - it's around 6km away from Cain at the time it departs.

M8: Mostly good, except there's no opportunity for Cain to be destroyed to fail the secondary objective. Could use some bombers launched from the station to present a threat.

M9: Same as M6. Not as uneventful, but still trivial as hell with good loadout + orders at mission start + personal strategy. Even on Insane my squad doesn't lose a single fighter in majority of attempts.

M10: The entire premise is pretty silly - I can't believe Lucifer couldn't spare a single volley to roast Leviathan and just move into Sol right away.

M11: Same problem as M5. Maybe having the bombers be in the middle of taking the 4th reactor out would actually present a challenge of shaking the fighters off vs killing the bombers quickly before they nuke Lucifer.

M12: Nothing wrong with it.


Ship/weapon balance notes:

Saudade: this weapon is completely useless right now. Three possible ways to fix it: 1. change its mechanics into the same ones as Infyrno 2. turn it from aspect to heat seeker 3. increase its range.

Manticore: buff to Scorpion's missile capacity (50% of Basilisk's instead of 25%) and nerf to Manticore's (33% of Basilisk's instead of 50%) makes this the worst fighter in Shivan arsenal at the moment, its sole saving grace being speed. Maybe increase its durability to match Scorpion's?
